Eluviation Eluviation is the general term for the transfer of soil material in solution
and involves two main processes, leaching and cheluviation. Leaching is the
process whereby readily soluble soil components, both organic and inorganic,
are ...

CHELUVIATION. Organic compounds, derived through the partial decomposition
of organic matter, are important agents in weathering. Some act because they are
acid and simply etch into minerals but for others, ions from the mineral actually ...
During cheluviation in podzols, clay is decomposed too. Moreover, a bleached
eluvial horizon may be formed by loss of iron oxides, resembling the eluvial
horizon formed during ferrolysis. During cheluviation, however, Al as well as Fe
are ...

Cheluviation Cheluviation is a combination of chelation and eluviation.
Cheluviation refers to the process of geometrical evolution by which minerals in
the soil are weathered and decomposed under the action of the chelating organic
, ...

podzolic soil processes, especially CHELUVIATION, while the B horizon is
divided into an upper part (Bh) dominated by the redeposited humus and a lower
part (Bs or Bfe) dominated by the redeposited iron, and to a lesser extent,
aluminum.

Strictly speaking it can involve the leaching of calcium carbonate (decaicification)
, chelates (cheluviation) and clays (lessivage). Rain can pick up atmospheric
substances and form vegetation. This makes it slightly acidic and in many cases
this ...

Hydrolysis by water containing carbon dioxide, which removes silica and basic
cations; • Cheluviation, which dissolves and removes especially aluminium and
iron by chelating organic acids; • Ferrolysis, a cyclic process of clay
transformation ...

Clays and Clay Minerals: Proceedings of the Conference
Bases, especially aluminum and iron, are more easily leached out of a Podzol
soil than silica due to a set of processes described by the term cheluviation (
Swindale and Jackson, 1956). Cheluviation refers to dissolution and chelation of
the ...

World Reference Base for Soil Resources: Introduction
The process of translocation ( 'cheluviation' ) and accumulation (known as '
chilluviation'), is usually shown by the occurrence of an albic horizon underlain
by a spodic horizon. The illuviation of organic compounds can often be
demonstrated ...
